Version “11" 46XX Interface
Output Format: IBM RS-485 serial input/output for the 4680 and 4690
(46XX) point-of-sale terminals
The Version 11 46XX interface can be used in several different ways. Both the
46XX terminal and the scanner must be configured to match each other.
Warning: Power to the scanner and 46XX terminal should be turned off
before making physical connection.)
The 4680 and 4690 series terminals have different types of physical ports for
connecting bar code scanners. Scanner ports include Port 5B, Port 17, and
Port 9? (? = A, B, C, or E). A Port 9 type connector is present on all versions
of the 46XX families of terminals. That is one reason it is the normal point of
connection for Metrologic scanners. Another reason is that there is enough 12
volt power available to operate many Metrologic scanners. If the terminal
configuration requires the use of a different physical port, for connecting bar
code scanners, contact Metrologic to get particular adaptor cable information.
No matter what port is used for physical connection, all devices use a common
communications bus inside the 46XX terminal. Each device uses a different
address when it must communicate. The terminal must be configured to look
for a device at a logical address.
The IBM 1520 mode/address was selected as a default because it was the first
IBM 46XX family scanner to support UPC/EAN, Code 39 and Interleaved 2
of 5. The Version 11 scanner formats Codabar, Code 128, and Code 93 using
the Code 39 function code designation supported by the IBM device driver for
this scanner type. Other emulation modes currently available are the Port 17
IBM 3687-2 fixed scanner and the Port 9B IBM 4500 CCD hand-held bar
code reader. Use one of these other emulation modes depending on which
operating system (4680.OS, 4690.OS, POS/DOS or DOS/RIPPS) is being
used at the site.
Note: Metrologic’s 46XX hand-held scanner models are typically
installed with adaptor cables that draw power from the terminal.
